First Layout 01/22/08: butt stock, handguards, delta ring, end cap - all from the real weapon. Front sight getting replaced. Classic Army metal receiver set. 21" CMI barrel.

The Classic Army metal receiver set for an AirSoft XM177 E2 Carbine - close enough.

Looking into the upper receiver.

Looking into the lower receiver.

layout with front sight fitted. 1/26/08

Two piece 21" barrel, RAP4 front sight, triangular end-cap, triangular handguards.

The sight and end cap had to be reamed somewhat to fit over the 7/8" barrel.
The barrel end will be tapped for a 3-prong flash-suppressor that will have to be manufactured.

Concept Drawing

The Automag.

Images of the Mag with comparisons to the receiver.

Closing up openings to pour JB Weld.


J.B.Weld epoxy filler fills the rear of the lowers so they can be drilled and tapped to receive the buffer tube.

The Classic Army upper has tabs to lock the rear into the lower. These are trimmed off. The DBoys upper is the same way and get's the same treatment.

The RAP4 front sight needs to be fitted to the CMI 21 inch barrel.

The A2 buttstock and it's buffer tube.

When the J.B.Weld is set the post is cut off. A hole is bored to 1-1/8" and tapped to 1-3/16"-16.

good color match

13/16 bit and 7/8-20 tap from Victor Machinery for A-5 threaded barrel.
Note: Genius that I am, I didn't get a bit with a reduced shank to fit the 1/2" chuck of my drill press and had to get another bit - don't do that.

FINALLY got a 20rd magazine.
Here it's already cut to length

The Airsoft receiver is made small and won't fit a real mag, so it got some file work to make it fit.

1 A1 grip and 2 A2 grips

The M16A1 laid out

The 13/16 hole threaded to 7/8-20 for the Tippman A-5 barrel thread.

The barrel screwed in.

The barrel seen from inside.

The M4A1 laid out

Sanding and grinding the upper to fit the AutMag body. Do a little, check, a little more, check, etc. There's not a lot of metal there, so care and patience are needed.

The plastic upper requires a different approach. High speed tools tend to make it melt, so sandpaper is wrapped around the Mag body and the upper is worked by hand.

Another 21" CMI barrel had this tip which will be reworked to better resemble the actual 3-prong suppressor shown on the right.

Should have left it alone, oh well it'll do till I get a better idea.

Making molds for the grip billets from card stock - 3/14/08.

placing the molds with white glue.

The move at the end of June put a hold on pretty much all my projects. All of them are petty much waiting for one new project to be completed - setting up the new shop. That's just about done - it's mid October! Now to figure out where everything got packed away!
New shop taking shape.
